A simple suboptimal control law is derived which provides an efficient way to the control of the multivariable Hammerstein model systems whose linear part is not necessarily minimum phase. A direct adaptation scheme is presented to implement the control law and the global convergence of the algorithm is established.","PeriodicalId":6395,"journal":{"name":"1988 American Control Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1988-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85747822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The image is first thersholded, using an automatic thresholding technique, to yield a binary image. Clustering analysis is then performed and small clusters that represent noise are removed. Geometrical properties of each cluster are calclulated using the method of moments. Overlapping targets are identified using a newly derived moment that is sensitive to distortions in ellipse-like sahpes (missile shape). The number of targets is estimated as the number of nonoverlapping clusters, and their centroid is calculated in each frame. A record of each target is kept till it leaves the field of view. Simulation studies are presented and the results indicate that the proposed approach has good tracking performance.","PeriodicalId":6395,"journal":{"name":"1988 American Control Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1988-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88560497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sufficient conditions under which optimal incentive strategy exists are given and the optimal incentive strategies are derived.

A common finding in biologically-oriented neural networks research is that many networks operate in parallel to ensure desired operating characteristics. Results on trajectory formation, sensory updating, and anticipatory compensation illustrate networks that are applicable in several performance domains (planned arm and speech movements, ballistic eye-movements) and that help explain data on several distinct but cooperative brain regions (frontal cortex, globus pallidus, cerebellum). In these systems whose fast dynamics are governed by slowly changing network transmission weights as well as by rapidly fluctuating external inputs, a major focus of research is how to ensure that short-term dynamics automatically regulate learning (transmission weight modification) in such a way that the system is guaranteed to develop along an adaptive trajectory.","PeriodicalId":6395,"journal":{"name":"1988 American Control Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1988-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89039581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a variation of the distributed computation model, the algorithm is shown to converge. As an important application, we also show how the algorithm is applied to optimal routing in a large interconnected data communication network. The aggregation/disaggregation method proposed results in a multi-level hierarchical clustering of a large network, which fits naturally the hierarchical topological structure of large networks. A numerical simulation of a 52-node network shows that the serial version of the algorithm, has 35% saving of the computational time as compared to a path-formulated gradient projection code developed by Bertsekas, Gendron and Tsai, which is among the fastest existing programs for path-formulated optimal routing.","PeriodicalId":6395,"journal":{"name":"1988 American Control Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1988-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84715910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we present a case study involving a polytope of polynomials carried out using the new results in [8]. More specifically, we consider a state space model describing a pair of coupled oscillators. Motivated by the fact that stability is guaranteed for small coupling, we consider the following question: How large can the off-diagonal interactions be before instabilty occurs? To this end, we use the new theory in [8] to generate bounds on the off-diagonal interactions under which stability is guaranteed. Our results indicate that these bounds increase as the frequency difference between the oscillators increases and as the damping increases.","PeriodicalId":6395,"journal":{"name":"1988 American Control Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1988-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87075031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
